Int. Cl. D04b .15/ 76 U.S. Cl. 66-50 4 Claims ABSTRACT F THE DISCLGSUREAn angularly adjustable eccentric stud mounting on a latch needlecircular knitting machine for and upon which a needle-driven inclinedrotary design wheel is journalled and wherein changes in the angularposition of the stud causes the design Wheel to be adjusted lengthwiseof its plane of inclination to thereby adjust the level to whichselected needles are raised by the design wheel.

The present invention relates generally to the art of knitting and moreparticularly to needle-driven inclined rotary design wheels of the typeused on circular latch needle knitting machines for selective needleraising, the invention providing a novel mounting for individual ones ofthe said Wheels whereby the position of the latter may be readilyadjustably moved to accordingly vary the level to which selected needlesare raised by the said wheels.

lIt is an object of the present invention to provide means whereby theposition of individual ones of the aforesaid design wheels may bereadily adjustably moved lengthwise of the planes of their inclinationwith the result that the level to which selected needles are raised willbe varied accordingly.

It is a further object of the present invention to provide an angularlyadjustable eccentric stud mounting for and upon which individual ones ofthe aforesaid design wheels may be rotatably journalled and whereinangular adjustment of the said stud will result in a correspondingchange in the position of its associated design wheel.

The above and other objects and advantages of the invention will befully apparent hereinafter, it being understood that the presentinvention is primarily concerned with a novel mounting to provide forthe adjustable positioning of inclined design wheels and the combinationtherewith, all as will be described in detail hereinafter, as shown inthe accompanying drawings which are illustrative of certain preferredembodiments of the stud mounting and as set forth in the appendedclaims.

Patented Nov. 24, 1970 ice FIG. 6 is a plan View of FIG. 5.

FIG. 7 is a plan view similar to FIG. 6 showing a modified form of thepresent invention, and

FIG. 8 is a plan view also similar to FIG. 6 showing another modied formof the present invention. In certain latch needle circular knittingmachines it 1s customary to provide for needle selection at the feedsthereof by the use of needle-driven inclined rotary design wheels toraise selected needles from one level to one or more other levels, thewheels being driven by progressive engagement with the butts of theneedles of the machine. Each inclined design wheel is rotatablyjoumalled upon the shank of a stud positioned perpendicularly to theangle of its inclination, the stud projecting upwardly from a forkshaped base extending radially outwardly from the circular cam sectionof the machine. The Wheel and its stud are adjustable radially of themachine along the fork shaped base to move the Wheel toward and awayfrom the needle cylinder of the machine and the needles containedtherein.

The present invention provides for an additional adjustment of theinclined design wheels in directions extending transversely of theradial adjustment above set forth and in such new adjustment the wheelsare moved lengthwise of their planes of inclination. The result of suchadjustment is to vary the level to which the needles are raised by thedesign wheels. The adjustment is accomplished in the present instance bythe use of specially fonmed studs the Shanks of which are eccentricallydisposed relative to their heads, however, it will be understood thatthe invention is not limited thereto.

ln the drawings, FIGS. 1 and 2, a portion of a circular cam section of alatch needle circular knitting machine is shown at 10, of which an upperface is inclined as shown at 11. Set in a radially extending milled slotin the face 11 and flush therewith is a radially extending open endedfork shaped member 12, the latter being retained in position in the camsection by means of a countersunk head screw 13 extending through asuitable Aaperture in the base of the fork 12 and into threadedengagement with the cam section 10. The fork 12 is provided with a pairof spaced parallel arms 14, 14 each of which is undercut at 15, 15 alongtheir length, the fork being adapted to slidably receive and toadjustably support the stud of the present invention between the armsthereof.

The stud, shown at 16, is provided with a square shaped head 17, a shortcircular shank portion 18 extending from and centered in the head 17 anda further circular threaded shank portion 19 in extension of and oflarger diameter than the shank 18, the shank 19 being eccentricallydisposed relative to the shank 1'8 and to the center of the head 17, theShanks 1S and 19 *being tangent to a common plane parallel to one side17a of the head. The center line of the head 17 and of the shank 18 isshown at 18a while the center line of the shank 19 is shown at 19a.

The shank 18 is received between the non-undercut portions of the arms14, 14 of the fork 12 and its length is such as to permit the said armsto be slidably received between the head 17 and the shank 19 of the stud16. The head 17 is of a size to fit between and to be lengthwise movablealong the undercut portions 15, 15 of the arms 14, 14 of the fork 12. Ashouldered bushing 20 is placed over the projecting sha-nk 19 and adesign wheel 21, part of which is shown in section in FIGS. l and 2, isplaced over the bushing, the wheel being retained in place by a washer22 placed over the shank 19 in contact with the bushing 20 and by a nut23 in threaded engagement with the shank 19. It will be obvious thatthis arrangement permits radial adjustment of the wheel 21 relative tothe cam ring 10 and to the needles in the needle cylinder of themachine.

As shown in FIG. l, the wheel 21 is in its uppermost position ofadjustment lengthwise of the inclined surface 11 relative to the camsection 10 and associated parts, including the needle operating cams(not shown), the stud 16 being disposed with the side 17C of its head 17visible from the open end of the fork 12, the center line 19a of theshank 19 being above the center line -18a of the shank 18 and of thehead 17. In order to place the wheel 21 in its lowermost position ofadjustment lengthwise of the inclined surface 11, the stud 16 is causedto be turned one hundred and eighty degrees from its position in FIG. lto its fposition in FIG. 3 wherein the head 17 is now disposed so thatits side 17d is visible from the open end of the fork and wherein thecenter line 18a is above the center line 19a. Similarly, in order toplace the wheel 21 in an intermediate position of adjustment, the stud16 is caused to be turned ninety degrees from either its position inFIG. 1 or in FIG. 3 to its position in FIG. 4 wherein the head 17 is nowdisposed so that its sides 17C and 17d are parallel to the arms 14, 14of the fork 12 and wherein either its side 17a (shown) or its side 17b(not shown) will be visible from the open end of the fork, the centerlines 18a and 19a coinciding when the parts are viewed as in FIG. 4.

It will be understood that the stud 16 and the parts thereon arewithdrawn (after rst loosening the nut 23) from the fork 12 in order tochange the angular position of the stud after which the stud isreinserted into the fork 12 and the nut 23 is made tight thereon(against washer 22 and bushing 20) to hold` the parts in adjustedposition. It will also be understood that during such angular adjustmentof the stud and wheel, radial adjustment of the stud and wheel can alsobe made at the same time, as may be required, in coordination with thesaid angular adjustment of the stud and the wheel. In

other words, as the Wheel is adjusted up and down to vary the level towhich needles are raised thereby, it may also be adjusted radially asrequired in order to maintain the proper relation of the needle buttstherewith. The adjustments provided by the present invention arerelatively small and permit the needles to continue to be taken by theadjusted wheel at their normal level of approach to the latter.

A modification of the stud 16 is shown in FIG. 7, this modificationproviding the head thereof with an additional pair of spaced parallelsides 17e and 17f which are formed by cutting off equal triangularportions from diagonally opposite corners of the head, the distancebetween the faces 17e and 17j being equal to the length of one side ofthe pre-cut head 17. With this modi- 4lication, the stud 16 may bedisposed in the fork 12 with one and with the other of the uncut cornersof its head visible from the open end of the fork to provide anadditional pair of adjustable positions for the wheel 21.

A further modification of the stud 16 is shown in FIG. 8 by means ofwhich two adjusted positions of the wheel may be obtained. Instead ofthe stud being formed with a shank 18, it is formed with-its olf centershank 19 extending directly from the head 17 (without a shank 18) withthe shank 19 undercut, as at 24, along one side thereof adjacent to thehead 17 and parallel to side 17a, the so undercut portion of the shankbeing received between the arms 14, 14 of the fork 12 with the side 17cor the side 17d of the head visible from the open end of the fork toprovide two adjusted positions for the wheel 21, these corresponding tothe positions thereof shown in FIGS. 1 and 3.

It will be understood that other means may ibe used to propide anadjustable mounting for the design wheel, for example, the shank of thestud may be made concentric with the center of its head and the bushingmay be formed with an eccentric aperture to t on the shank of the studwhereby angular positioning of the bushing will provide for theadjustment of the design wheel.
